The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8. What is the ideal efficiency of the engine? Use

vodomira [7]

Answer:

e=58%

Explanation:

Given data

The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8.

Solution

We want to calculate the ideal efficiency of the engine when ratio of heat capacity for gas used γ=1.40. Ideal efficiency (e) of the Otto cycle given by:

$e=1-(\frac{1}{r^{Y-1} } )\\$

Substitute the given values to find efficiency e

$e=1-\frac{1}{8.8^{1.4-1} } \\e=0.58\\$

e=58%

An automobile is driven on a straight road, and the distance traveled by the automobile after time t=0 is given by a quadratic f

TEA [102]

Answer:

$Velocity = \frac{s(8)}{8}$

Explanation:

Given

$0 \leq t \leq 12$

Required

Determine the velocity when t = 8

This type of velocity is referred to as an instantaneous velocity.

In this case, it is calculated using

$Velocity = \frac{Distance\ at\ 8 second}{t = 8}$

Given that s(t) models the distance;

s(8) = distance at 8 seconds

So;

$Velocity = \frac{s(8)}{8}$
